liminis join this supernatural rp set in the aftermath of a direct attack by demonkind!! apps required, but it's an awesome plot-based game with tons of worldbuilding and mods who encourage character development and original ideas.
as for lines? i'd love this guy's ex-wife (a filipina), a low-ranking member of the collective he ends up mentoring, an infernal he's attached to in the mundane world even if they're supposed to be enemies, someone who works at his watchmaking/smithing business (an apprentice?), and generally any and every connection you can think of! i'm just spitballin' ideas, here.
